GRAIN-DOOR FOR CARS.

LWN/726.

Specification of Letters Patent.

Patented Nov. '7, 1911.

Application filed October 26, 1910. Serial No. 589,101.

To all fte/wm` z5 may concern.'

Be it known that I, SWAN IoNTUs OLSON, a subject of the King of Great Britain, residing at Kenora, in the Province of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Grain-Doors for Cars; and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved grain door for cars, and to this end, the invention consists of the novel devices and combinations of devices hereinafter` described and defined in the claims,

In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a view in elevation, looking at the outer face of the improved door and showing a portion of a door frame; Fig. 2 is a horizontal section taken approximately on the line #-002 of Fig. 1; Fig. 3 is a view looking at the parts shown in Fig. 1 from the inside of the car; and Fig. 4 is a view corresponding in the line of its section to Fig. 1, but showing the door released and moved slightly outward from its closed position.

The numeral 1 indicates the frame of one of the side door openings of the car, to which the door is applied. The vertical posts of this door frame are provided on their opposing edges with vertically spaced lock seats 2, and on their inner faces they are provided with vertically extended guides 3 at the lower extremities of which are stops 4,

The body of the grain door is indicated as an entirety by the numeral 5, and this door body is of such width that it will pass freely through the door opening when swung laterally inward and outward. The stops 4 are approximately on a level with the upper edge lof the door 5 when the latter is closed. Mounted to slide vertically on the guides 3 are hinge blocks 6 in which the upper laterally bent ends of hinge irons or brackets 7 are pivoted. The lower ends of these hinge irons 7 are bolted or otherwise rigidly secured to the upper edge portion of the door 5, so that the latter is adapted to and connected thereto by hinges 8 are vertically extended joint plates or strips 9 which, when the door is closed, are adapted to overlap the inner faces of the door posts and thus form grain tight joints between the door and the said door posts. These joint plates extend from top to bottom of the door. These joint plates 9 are provided with projecting stems 10 having perforated heads 11 adapted to be passed outward through perforations 12 in the edges of the door 5.

At each vertical edge, the door 5 is provided with a vertically spaced pair of forked lock bolts 13, the prongs of which, as shown, work through guide lugs 14 and the stems of which work through guide lugs 15 of metallicl bearing plates 16, which latter are bolted or otherwise rigidly secured on the outer face of the door. The relatively long prongs of the lock pieces 13 are adapted to enter the seats 2 in the door posts, and the relatively short forks of the said lock pieces have beveled or tapered ends and are adapted to be passed through the perforated heads 11 of the projecting stems 10.

The stems of the lock bolts 13 are connected by oblique rods 17 to a common lock lever 18. This lock lever is pivoted at 19 to a suitable bearing bracket 20 secured on the outer face and at the central portion of the door 5. By movements of this lever 18, the four lock pieces 13 may be moved simultaneously outward or simultaneously inward. To lock the said lever in a position close to the door, as shown in Figs. 1 and 2, its free end is arranged to work between the prongs of a lock bracket 21 secured on the outer face of the door, and a lock pin 22 is passed through coincident perforations in the said lever 18 and in the lugs of the said bracket 21. If desired, a car seal may be applied to the lower end of the lock pin 22, to prevent removal thereof without breaking of the seal.

In the closed position of the door, shown in Figs. 1 and 2, the pronged lock pieces 13, as is evident, securely hold the body of the door in its closed position and the joint plates 9 clamped against the door and against the inner faces of the door posts. Outward movement- -of the door is then prevented both by the engagement of the long prongs of the said lock pieces with the door posts and by engagement of the joint strips 9 with the door posts. To open the door, the pin 22 must first be removed and then the lever must be moved outward into the position shown in Fig. 4. This movement of the lever draws the forked lock pieces 13 into inoperative positions and releases the body of the door from the door posts and the joint strips 9 are then permitted to move on their hinges so that they will clear the door posts and pass through the door opening with the body of the grain door. When the grain door is out of use, the hinge blocks 6 may be slid upward on the guides 3 toward the top of the car and then the door may be swung against the top of the car and secured thereto by hooks or other suitable devices.

The door is of simple construct-ion, is eilicient for the purposes had in view and may be opened with such ease that there will be no temptation to break the door in the opening operation.

What I claim is:

1. The combination with a door frame and a door arranged to move laterally through the same, of joint strips applied to overlap t-he door posts and adjacent edges of the door, heads applied to said joint strips and projecting through said door, and lock pieces movably mounted on said door and arranged to engage with the said heads and with said door frame to thereby lock said door and the said joint strips in respect to said frame.

2. The combination with a door frame having lock seats in the opposing faces of its posts, of a door adapted to move laterally through the opening of said door frame, joint strips hinged to the said door and adapted to overlap the inner faces of the door posts, perforated heads secured to said joint strips and projecting through passages in the said door, forked lock pieces engageable with the seats in said door post-s and with the said perforated heads, and means for imparting simultaneous movements to the said lock pieces and for securing the same in operative positions, sub stantially as described.

3. In a grain door structure, the combination with a door body adapted to pass laterally between the door posts, of vertical joint strips hinged on the inner side of said door body, near its vert-ical edges and normally overlapping the door posts, stems having perforated heads carried by said joint strips and adapted to pass through holes in the door body, and sliding lock pieces on the outer side of said door body adapted to engage the said perforated heads.

4. In a grain door structure, the combination with a door body adapted to pass laterally between the door posts, of vertical joint strips hinged on the inner side of said door body near its vertical edges and projecting beyond said edges so as to overlap the door posts, stems carried by the said joint strips and provided with perforated heads adapted to pass through holes in said door body, sliding lock bolts on the outer side of said door body adapted to engage the said perforated heads and also to enter seats in the door posts, and a lever with links connected to said lock bolts for simultaneously operating the saine.

In testimony7 whereof I affix my signature in presence of two witnesses.
